Quickstart
First, run PostgreSQL, set environment variables and create database. For example using docker:
export POSTGRES_DB=rwdb POSTGRES_PORT=5432 POSTGRES_USER=postgres POSTGRES_PASSWORD=postgres
docker run --name pgdb --rm -e POSTGRES_USER="$POSTGRES_USER" -e POSTGRES_PASSWORD="$POSTGRES_PASSWORD" -e POSTGRES_DB="$POSTGRES_DB" postgres
export POSTGRES_HOST=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' pgdb)
createdb --host=$POSTGRES_HOST --port=$POSTGRES_PORT --username=$POSTGRES_USER $POSTGRES_DB
Then run the following commands to bootstrap your environment with poetry:
git clone https://github.com/nsidnev/fastapi-realworld-example-app cd fastapi-realworld-example-app poetry install poetry shell
Then create .env file (or rename and modify .env.example) in project root and set environment variables for application:
touch .env echo DB_CONNECTION=postgresql://$POSTGRES_USER:$POSTGRES_PASSWORD@$POSTGRES_HOST:$POSTGRES_PORT/$POSTGRES_DB >> .env echo SECRET_KEY=$(openssl rand -hex 32) >> .env
To run the web application in debug use:
alembic upgrade head uvicorn app.main:app --reload
Deployment with Docker
You must have docker and docker-compose tools installed to work with material in this section.
First, create .env file like in Quickstart section or modify .env.example.
POSTGRES_HOST must be specified as db or modified in docker-compose.yml also.
Then just run:
docker-compose up -d db docker-compose up -d app
Application will be available on localhost in your browser.
Web routes
All routes are available on /docs or /redoc paths with Swagger or ReDoc.
Project structure
Files related to application are in the app or tests directories.
Application parts are:
app ├── api - web related stuff. │ ├── dependencies - dependencies for routes definition. │ ├── errors - definition of error handlers. │ └── routes - web routes. ├── core - application configuration, startup events, logging. ├── db - db related stuff. │ ├── migrations - manually written alembic migrations. │ └── repositories - all crud stuff. ├── models - pydantic models for this application. │ ├── domain - main models that are used almost everywhere. │ └── schemas - schemas for using in web routes. ├── resources - strings that are used in web responses. ├── services - logic that is not just crud related. └── main.py - FastAPI application creation and configuration.
